Hybrid techniques provide “shining example of modern concrete construction”

Offsite Hybrid “kit of parts” approach provides considerable customer and environmental benefits

Despite the complexities of the Capella project in Cambridge, a combination of effective BIM implementation and the utilisation of offsite manufactured precast components enabled the structural package to be delivered in only eight months, according to a recent report in Concrete Magazine.

The article, by Norman Brown, describes Capella as “A shining example of modern concrete construction” and focusses on a number of key benefits provided by the Hybrid approach taken by PCE Ltd.

These included:-

  • Effective BIM implementation: this enabled the integration of an “extremely complex” services strategy.
  • Offsite component manufacture: the structural package took a mere 8 months with the anticipated onsite in-situ concrete programme option being reduced by 20 weeks.
  • The “Kit of parts” approach: this allowed “exacting technical requirements to be achieved in challenging locations.”
  • Carbon footprint reduction: on-site savings in personnel and deliveries and considerable reduction of site waste “gives off-site construction a major environmental benefit compared to full on-site construction processes.”

Vibration resistance requirement

PCE worked, according to the report, with Professor Paul Reynolds, the University of Exeter‘s head of engineering who is a specialist in the field of structural vibration. This enabled the project to effectively address one of the main design criteria – floor plate vibration control due to the very sensitive laboratory equipment that would be used within the building.
